If you're deleting the VPC and its associated components, we recommend
that you detach the virtual private gateway from the VPC and delete the
VPC before deleting the VPN connection. If you believe that the tunnel
credentials for your VPN connection have been compromised, you can
delete the VPN connection and create a new one that has new keys,
without needing to delete the VPC or virtual private gateway. If you
create a new VPN connection, you must reconfigure the customer gateway
using the new configuration information returned with the new VPN
connection ID.
